Voting Information for Montana

Don’t miss your next election!

Voter registration forms in Montana must be postmarked by Oct. 5th. If you would prefer to vote by mail your request must be received by Nov. 2nd at 12pm. We recommend getting your application in as soon as possible.

Missed the registration deadline? No problem, you may register to vote in person with valid ID on Election Day.

Vote-by-mail systems are different in every state. It is critical that you follow directions and pay attention to the details, or your ballot could be challenged or even tossed.

The signature on your ballot must match your DMV signature, or signature that is on file with your voter registration if you do not have a state-issued ID. If your signature does not match, your ballot could be tossed.

Here are some important things to know about voting by mail in Montana:

Don't forget to put postage on your ballot. You are responsible for adding stamps.

Your state has a "received by" deadline of Tuesday, November 3rd. The post office suggests that ballots are mailed at least two weeks prior to make the "received by" deadline. Don't wait! You may also return your ballot via a delivery service, like FedEx or UPS, to ensure delivery date.

Your state gives you the opportunity to "cure" any challenge to your ballot. This means if there is something wrong with the signature on your ballot, the state is required to contact you and give you options to remedy your ballot. Your clerk will provide step-by-step instructions for curing your ballot. Be sure to check your mail and messages (phone and email) for incoming communication from your election's office to have the opportunity to cure. You will be contacted if there is a challenge to your ballot. You must "cure" the challenge before 8 p.m. on Election Day. Get your ballot in early so that you have a chance to address any challenges.

Your state offers electronic, barcode ballot tracking services so you can make sure your ballot gets counted. Click here to access.
